Introduction
We built these 800W halogen lamps for one reason: to replace the ones in PET blowing machines. No fuss. No re-engineering. Just a straight swap that works. These aren’t some generic heater you can stick anywhere. They’re made to slide right into the existing spot in your machine and deliver the exact heat you need, every single time.
Let’s talk about the power
The 800W rating isn’t random. It’s the sweet spot for heating PET preforms. Enough power to soften the material fast, but not so much that you’re pushing your machine’s power supply to its breaking point. And the voltage? That’s critical. If your machine runs on a high-voltage circuit, the lamp has to match. Get it wrong, and you’ll either get weak heat or the lamp will burn out way too soon. The size is just as important. We set the overall length and dimensions to match the standard brackets and reflectors. So when it’s time to replace one, you just pop it in. No messing with clamps, wiring, or trying to make parts fit.
What’s inside
Inside the quartz envelope, you’ve got a halogen element. It runs hotter and cleaner than a standard tubular heater. The halogen cycle keeps the filament stable, which means the output stays consistent over the life of the lamp. We also added a high-temperature coating to the quartz. This helps prevent hot spots and handles the stress of rapid heating and cooling cycles. And the R7s connector? It’s the industrial standard for a reason. It handles the current, makes a solid connection, and makes the whole thing easy to wire and swap out on the floor.
How it feels on the floor
On a PET blowing line, the preform heater has to do its job in a tight window. You need even heat, fast. An 800W halogen lamp brings that. It responds quickly and packs a lot of heat into a small space. That means your heating zone stays tight and predictable. The result? Stable temperatures across the preform, which helps you keep wall thickness consistent and cut down on scrap. But let’s be real—800W halogen lamps throw off a lot of radiant heat. So your machine’s cooling and shielding have to be up to the task. If the cooling isn’t enough, the ambient temperature climbs, and that shortens the lamp’s life. Our goal is simple: make a lamp that runs at the right wattage, fits the space, and is quick to replace. For you, that means less downtime and fewer headaches when it’s time to change over.
